On December 15, 2022, the California Public Utilities Commission passed an overhaul of the net metering program for the state’s investor-owned utilities. The changes replaced the long-standing net energy metering (NEM) tariffs with a net billing tariff (NBT) structure—colloquially known as “NEM 3.0”—which significantly reduces the compensation for behind-the-meter solar photovoltaic (PV)...

To meet clean energy goals, states will need significant capital. Federal funding from the Inflation Reduction Act and the Infrastructure Investment and Jobs Act will make some of this capital available. States may wish to consider leveraging their state clean water revolving funds to finance even more clean energy improvements. New York and Pennsylvania have used this innovative mechanism to...

Price-based demand response (DR), or time-varying rates, is an underutilized resource that could substantially contribute to load flexibility for electricity systems. But most utilities have not yet captured these benefits in electricity system planning. Berkeley Lab's new technical brief, “The use of price-based demand response as a resource in electricity system planning,” finds that... Read more

In A Thousand Mile Walk to the Gulf, John Muir elegantly discussed the limits of scientific characterization of the wind, saying: "The substance of the winds is too thin for human eyes, their written language is too difficult for human minds, and their spoken language mostly too faint for the ears." Over 100 years later, scientists still face challenges describing, tracking, and predicting wind... Read more
